Description

The present invention relates to a foam inhibitor capable of suppressing the foaming property of an aqueous composition containing a surfactant, and further includes benzyl acetate, linalool, cis-3-hexenol, phenylethyl alcohol (Rose P), cineol. The present invention relates to an antifoaming agent comprising a component selected from the group consisting of cis-3-hexenyl acetate.

  Glasses such as skin and hair, tableware, and various cleaning agents for home use effectively utilize properties such as an increase in volume due to foam, a decrease in flowability, ease of visual recognition, and soft touch when washed. Also, in the formulation of general cosmetics, foam is used to improve the touch and convenience during use, as seen in hair styling agents and shaving treatment agents. On the other hand, while forming bubbles during use, it may be desired to quickly reduce the bubbles.

  For example, during the cleaning operation, the amount of foam that is produced when the detergent composition is being stirred may be so excessive that it adversely affects the cleaning effect of the detergent composition. In an example of this improvement (Patent Document 1), a foaming inhibitor containing a specific dicarboxylic acid and a silicone antifoaming agent in the cleaning composition is proposed. In the detergent industry, there is a tendency to make the cleaning agent compact, and these products are often highly foaming products containing a large amount of a surfactant, and especially in the rinsing process after cleaning. There are problems such as making the consumer feel that a large amount of foam remaining for a long time leaves an excessive amount of surfactant, and requiring a large amount of water in the rinsing process. In an example (Patent Document 2) in which this improvement has been made, a foaming inhibitor containing a silicone foaming inhibitor and a fatty acid foaming inhibitor has been proposed. These suppress foaming of the cleaning composition. However, in addition to the cleaning agent, bubbles may be formed during use or accidentally, but it may be desirable to quickly reduce the bubbles. For example, in water-soluble products such as skin lotions and liquid fragrances, surfactants are generally used to uniformly dissolve and disperse active ingredients and medicinal ingredients in products, so products may be accidentally dropped, For example, bubbles may be generated when shaken to give an unpleasant impression to consumers. In order to solve such problems, there has been a demand for a foam suppressant that can be used in various forms of products other than cleaning agents.

  Commonly used antifoaming agents include silicone antifoaming agents and ethanol. Silicone antifoaming agents are difficult to dissolve in water. Additional surfactants may be required, and the cost may increase. Moreover, ethanol needs to be blended in a large amount in order to obtain a foaming suppression effect, which may affect the properties of the product itself.

On the other hand, benzyl acetate, linalool, cis-3-hexenol, phenylethyl alcohol (Rose P), cineol, and cis-3-hexenyl acetate are compounds that are generally used as perfumes. These perfume compounds are added as a masking agent for a cosmetic raw material or by imparting a fragrance to add comfort during use or to differentiate a product. However, there is no concept of using it as a foam inhibitor in cosmetics such as detergent compositions. Furthermore, the use for the purpose of suppressing foaming and the method of use for achieving foaming suppression have not been studied at all, depending on the combination and ratio of ingredients when manufactured as a perfume composition. On the other hand, the foaming property and foam retention may have the opposite effect to those desired.

  Perfumes are diverse and have different structures, so even if the required scent can be scented, depending on the type of perfume, the original foaming and foam retention of the cosmetic base itself can be improved. There was a case of letting me. Accordingly, it is an object of the present invention to provide a foam suppressant that particularly suppresses the persistence of foam without improving the foaming and foam retention of the cosmetic base itself.

  In order to solve the above-mentioned problems, the inventors have conducted research on the search for a fragrance composition that is effective as a foam suppressant for an aqueous composition containing a surfactant. A foam-suppressing agent comprising a component selected from the group consisting of linalool, cis-3-hexenol, phenylethyl alcohol (Rose P), cineol, and cis-3-hexenyl acetate. As a result, the present invention has been completed. Hereinafter, the present invention will be described in detail.

  A foaming inhibitor comprising a component selected from the group consisting of benzyl acetate, linalool, cis-3-hexenol, phenylethyl alcohol (Rose P), cineol and cis-3-hexenyl acetate of the present invention. Can suppress the foamability and / or the persistence of the foam of the aqueous composition containing the surfactant. In addition, mass production methods have been established, are easily available, and do not have an unpleasant odor, so that they can be widely applied.

    The foaming inhibitor in the present invention suppresses foaming caused by the main surfactant and / or foam persistence, and in particular suppresses foam persistence.

  The foam suppressor of the present invention may contain at least one selected from benzyl acetate, linalool, cis-3-hexenol, phenylethyl alcohol (Rose P), cineol, cis-3-hexenyl acetate, Two or more kinds may be used in combination.

  Benzyl acetate, linalool, cis-3-hexenol, phenylethyl alcohol (Rose P), cineol, cis-3-hexenyl acetate used as the foam inhibitor of the present invention can be synthesized by known methods, Since it is generally commercially available, it can be easily obtained. Furthermore, these compounds are known to be contained in plant essential oils and the like, and fractions of these essential oils can also be used.

  The foaming inhibitor of the present invention is used in a composition containing a surfactant for the purpose of suppressing foaming by the surfactant and / or persistence of the foam. The surfactant in the present invention has both a hydrophilic portion (hydrophilic group) and a lipophilic portion (lipophilic group) in the same molecule, and has the property of adsorbing with an orientation at the interface. There is a foaming property, and two or more types may be mixed. Specifically, anionic surfactants (carboxylates, alkyl sulfates, polyoxyethylene alkyl ether sulfate esters, alkyl carboxylates, alkyl sulfonates, alkyl sulfate esters, dialkyl sulfosuccinates, alkyl phosphates) Salt, N-acylalanine salt), cationic surfactant (tetraalkylammonium salt, alkyltrimethylammonium salt, dialkyldimethylammonium salt, alkylpyridium salt), amphoteric surfactant (carboxylic acid type amphoteric surfactant (amino type) , Betaine type), sulfate ester type amphoteric surfactant, sulfonic acid type amphoteric surfactant, phosphate ester type amphoteric surfactant), nonionic surfactant (polyoxyethylene alkyl ether and other ether type nonionic surfactants) Agent, polyethylene glycol Ester-type nonionic surfactants such as boronic acid esters, etherester-type nonionic surfactants, block polymer-type nonionic surfactants, nitrogen-containing nonionic surfactants), other surfactants (natural interface) Activators, derivatives of protein hydrolysates, polymer surfactants, surfactants containing titanium and silicon, fluorocarbon surfactants) and the like.

  The foam inhibitor of the present invention is preferably blended in an amount of 0.0001 to 50% by mass with respect to the surfactant amount. When the amount of the foam inhibitor is less than 0.0001% by mass, usually a sufficient effect cannot be obtained. Moreover, since an effect does not change in particular at 50 mass% or more, it is not necessary to mix | blend the foam inhibitor of this invention with the quantity exceeding 50 mass% with respect to surfactant.

  The blending amounts of benzyl acetate, linalool, cis-3-hexenol, phenylethyl alcohol (Rose P), cineol, and cis-3-hexenyl acetate used as the foam inhibitor of the present invention are set to 0. It is 0001-10 mass%, More preferably, it is 0.0001-3 mass%. When the amount is more than 10% by mass based on the cosmetic product, the cosmetic product may cause phase separation and deteriorate the appearance, or the fragrance may be too strong to cause discomfort when using the cosmetic product. . On the other hand, when the amount is less than 0.0001% by mass with respect to the cosmetic product, the effect as a foaming inhibitor cannot be obtained sufficiently. When the fragrance is already blended in the cosmetic product, it is preferable to adjust the blending amount appropriately so as not to disturb the fragrance.

  It can be appropriately used in combination with a commonly used foaming inhibitor, for example, a silicone foaming inhibitor such as dimethyl silicone, a higher alcohol such as octyl alcohol or cyclohexanol, ethanol, ethylene glycol, or the like.

(Evaluation of foaming and foam sustainability)
In order to confirm the foaming property of the aqueous surfactant composition and the foam persistence when the foaming inhibitor of the present invention was included, the following tests were conducted.

A sample was prepared by adding 0.05% of the foam inhibitor of the present invention to a 0.3% sodium dodecyl sulfate (SDS) aqueous solution. Place a glass funnel (3 mm in diameter) on top of a 100 ml graduated cylinder, drop 50 ml of sample through the funnel into a 100 ml graduated cylinder, the foam height (H1) immediately after placing it, and the foam height after 30 minutes. (H2) was measured. The foaming property was evaluated by the height (H1) of the foam immediately after putting, and the persistence of the foam was calculated by the following formula.
Foam persistence (%) = [H2] / [H1] × 100

(Comparative example)
In the cosmetic field, ethanol and dimethyl silicone (Toray Dow Corning Silicone Co., Ltd., trade name: SH200C-10cs) used as a foam inhibitor are similarly evaluated for foamability and foam persistence. Went.

  As shown in Table 1, the SDS aqueous solution to which benzyl acetate, linalool, cis-3-hexenol, phenylethyl alcohol (Rose P), cineol, cis-3-hexenyl acetate was added was compared with the SDS aqueous solution to which these were not added. In addition, the foamability is similar, but the persistence of the foam is reduced. In addition, the foam persistence is lower than that of ethanol and is similar to that of dimethyl silicone, and it suppresses the persistence of foam in the same manner as the foam suppressor used in the cosmetic field. It was confirmed that it can be used as a foam inhibitor.

  The present invention can suppress foam retention and form foam, but can be applied to general products that want to reduce the persistence of the formed foam and suppress the foamy state.
